When a host is booted on a network which MAAS controls the machine goes into enlistment which gathers basic information about the system. If an IPMI, HP Moonshot, or Facebook Wedge BMC is detected MAAS creates its own user to interact with the BMC. It appears MAAS is detecting that the IBM Server X3650 M4 is using an IPMI BMC and has configured it with a MAAS username and password.

A rack controller must be on the same network as the BMC. You can test this by SSHing into the machine running the rack and executing the following command
$ ipmipower -s -D LAN_2_0 -h 192.168.70.125 -u maas -p l005vVhVl2

The MAAS logs may also provide more information, they are available in /var/log/maas

MAAS Region and Rack controller are installed on another Server and I’d like to use 4 IBM Server X3650 M4 as node to install Openstack, both of them are on the same network. of MAAS server.
My issue is after that the node is enlistmented on MAAS, the node don’t start after I run the commission. it rest down.

Ricardo- make sure the IPMI is enable in the IMM setting (bios), reboot the system (M3650 M4) and make sure the IMPI is enable in the IMM configuration, that can cause the maas not to power on/off the server. leet me know thanks

now my Q is:
The lab has to have 3 networks: one for IPMI management; one for the physical interface (eno2) and one for second one (eno3). Or IPMI and eno2 can be have the same IP address or network?

MAAS only needs to be directly connected or routed to the IPMI network. In other words, you can put a single rack controller in the IPMI management network and MAAS will be able to power manage your machines.

my opinion: maybe there is a set to make on the Bios to indicate on which interface we want actived the IMM??? in this way the dedicated option is correct, if it is shared I think that the IMM address IP can be reached from each physical interface. no?
back to the IBM 3650M4 I’ve the following network interfaces:
1/IMM
2
3
4
IMM2
I want to change the cable to IMM2 and check

A dedicated systems-management network port might not be available on your server. If your hardware does not have a dedicated network port, the shared setting is the only IMM2 setting available. On the Network Configuration screen, select Dedicated (if applicable) or Shared in the Network Interface Port field.
